CLOSET-RINSING APPARATUS.

T 0 all whom it may concern:

Be it known that I, ROBERT STIOKDORN, a citizen of Germany, residing at Dusseldorf, Germany, have invented new and useful Improvements in Closet-Rinsing Apparatus, of which the following is a specification.

This invention relates to a novel apparatus for rinsing water closet bowls in a quick and reliable manner.

In the accompanying drawing: Figure 1 is a perspective view of a water closet provided with my improved rinsing apparatus; Fig. 2 a vertical section through the valve casing, showing the tank in view and partly broken away; Fig. 3 a vertical section through the valve casing, taken at right angles to Fig. 2, and Fig. a a similar section, showing the parts in a different position.

The water tank 9, is preferably made in the form of a short horizontal cylinder of comparatively large diameter. Tank 9, is completely countersunk ithin wall TV, in such a manner that its flat circular head extends parallel to said wall. At its bottom, tank g, communicates with a T-shaped pipe 10, into the upper leg 10, of which is tapped a cylinder or valve casing Z). The latter is connected to a suitable water supply pipe 2, controlled by valve .2. Cylinder b, embraces the collar h, of a vertically reciprocating hollow piston It. Collar it, plays between upper and lower stufiing rings (Z, and m, which are fitted into the cylinder at its upper and lower ends respectively. Below collar h, piston h, is provided with water outlet openings a, while above such collar, water inlet openings 6, are formed within piston It. From the latter extends downwardly a stem .9, carrying a packed ring ]L2, and a cupshaped valve i), which snugly fits into outlet spout u. The upper end of piston it, is provided with a hollow cylindrical extension :0, movable within a stufling box y, of cylinder Z). To the top of extension 00, is secured a hood 0, beneath which air openings 1, are formed that communicate with the interior of extension 60, and piston h. lVithin the former is contained a bell-shaped float valve 0, which, when raised, abuts against a washer f, and thus prevents communication between ports 1, and the interior of extension m.

The parts normally assume the position shown in Fig. 2, so that openings a, and c, are located above ring m, to shut the water supply ofi tank 9, while the latter is free to communicate with the outlet u, through Specification of Letters Patent.

opened valve Q). If it is desired to flush the closet bowl, a suitable hand lever p, is depressed to lower piston it, into the position shown in Fig. 3. ater will now enter cylinder Z), through pipe 2, and will flow through openings 6, hollow piston h, and openings a, into pipe w. As valve 2;, is closed the water will enter tank 9, in which the pressure will gradually rise owing to the compression of the air contained therein, until said pressure becomes suiiicient to lift piston it, into the position illustrated in Fig. 2, which movement takes place owing to the difference in area of ring 7L2, and valve '2). In this way the water supply is automatically cut OE and valve 4), is opened to permit the discharge of the water contained within tank 5/, through spout u. The relative position of ports and valve o, is such that the ports are closed by ring m, prior to the opening of valve 0), so that any communication between the water supply and the contents of the bowl is effectively prevented.

The air inlet device provided at the top of piston it, prevents the return of the contents of the bowl into the water service pipe 2, when either a pipe bursts or when the water supply is turned off. It will be seen that normally bell 0, is by the water pressure forced against washer f, thus preventing communication between the interior of extension 00, and the outer air. Bell 0, remains in the raised position during the alternate filling and emptying of tank g. When, however, the service pipe breaks, or when the water supply is turned off, the water will flow out of cylinder 00, and float 0, will consequently fall to establish communication between cylinder w, and the atmosphere, (Fig. t). In this way the air valve allows drainage of the service pipe by preventing formation of a vacuum in the chamber b.
